As many of you will know I'm interested in the science of crying and finding out more about what makes people cry and how often they cry. To this end I have a fairly comprehensive questionnaire which I'd be hugely grateful if folks on this forum would consider completing.

It is big and will take a bit of time to complete - roughly 30 minutes or so - but you can save and return so you don't need to do it in one sitting.

The URL is - www.surveyhero.com/c/crying 

It is completely confidential - if you are comfortable doing so however I'd be grateful if you would consider adding your forum username in the last section. It would be interesting for me to tie up the responses to posts you have made on the forum in the past.

Huge thanks in advance for your help - it's very much appreciated - any questions fire away, Once I get enough responses I'll be sure to share some of the statistics that emerge. I will not share any personal or individual information from individual responses.
